How to Convert Serial.printf() line into String???

[charnjit]

if we have some information lines like this

  Serial.printf("Read %s into memory at %08X; %d bytes\n", SMP_WAV[i], SMP_addr[i], sizes[i]);

can i convert it into string for use in single line function of ili9141 display.
for example any idea like this .... this funtion to print line on display

     void TFT_INFO (String INFO)   {
        tft.fillScreen(ILI9341_BLUE);
        tft.setCursor(10, 100);
        tft.setTextColor(ILI9341_WHITE, ILI9341_WHITE);   
        tft.setTextSize(3);
        tft.println(INFO);   
        tft.setTextColor(ILI9341_WHITE, ILI9341_YELLOW);
                                 }

i want to write a single line some thing like

TFT_INFO ("Read %s into memory at %08X; %d bytes\n", SMP_WAV[i], SMP_addr[i], sizes[i]);

.
means write one line TFT_INFO(); instead of repeat 6-7 lines of tft.xxxx();
I want to get String INFO as full line of output of

  Serial.printf("Read %s into memory at %08X; %d bytes\n", SMP_WAV[i], SMP_addr[i], sizes[i]);

is it possible ???????

If I’m understanding correctly, see snprintf().

THANK YOU @shawn.
it is one what i want

  Serial.printf("Read %s into memory at %08X; %d bytes\n", SMP_WAV[i], SMP_addr[i], sizes[i]);
            snprintf(buffer, sizeof(buffer),"Read %s into memory at %08X; %d bytes\n", SMP_WAV[i], SMP_addr[i], sizes[i]); TFT_PRINT_INFO(buffer);

working as i want.
